Yeah you are one of a kind Stella, or should I say several of a kind lol!

I agree, I think perhaps we are all in the process of constantly re-creating ourselves. At least I feel I am.
When I was a teenager I made a pro-active decision to plan my life in periods of five year spells- -so every 5 years I changed my job/career. Started a new hobby and a new sport. Each of these depended upon my age ability.
For example, as a young man I did sword fencing as a sport /hobby. The sport is so fast that at 27 you are just too slow. So I quit and took up Golf instead and so on. In this way, perhaps similar to you changing your character identities, I feel I have l lived different lives. I ma sharing them on this platform now.
However,as with yourself, creativity has always been my main theme and is the one constant factor that hold everything together. The glue if you like.

Children change us though, there is no escaping that. Never again can we think only about ourselves and that is a game change.

To the friends I have who I cherish the most I often say to them "You are one of a kind my friend, I hope you dont change"
With though perhaps I would say "Hope you keep changing Stella" Lol!
